So, I have a .txt file which contains over 1200+ lines of building id's, ipaddress. So, to be clear, the format of data in my txt file example looks like this:

00Q0VA,10.1.1.2
00Q0VB,10.1.1.3
00Q0VC,10.1.1.4
etc....

What I need is a DOS script which takes the all the data from this one txt file and output into another SINGLE txt file ONLY with adding lines which include the static data from the original modified to be imported into nagios. So, to be clear using the example above, the single output file should look identical to this:

define host{
use pos_mgr_template ; Inherit default values from a template
host_name 00Q0VA ; The name we're giving to this host
alias 00Q0VACAFE ; A longer name associated with the host
address 10.1.1.2 ; IP address of the host
}

define host{
use pos_mgr_template ; Inherit default values from a template
host_name 00Q0VB ; The name we're giving to this host
alias 00Q0VBCAFE ; A longer name associated with the host
address 10.1.1.3 ; IP address of the host
}

define host{
use pos_mgr_template ; Inherit default values from a template
host_name 00Q0VC ; The name we're giving to this host
alias 00Q0VCCAFE ; A longer name associated with the host
address 10.1.1.4 ; IP address of the host
}

etc....
Notice the inputted change lines are the 3rd (host_name), 4th (building ID with the word "CAFE" appended to it), and 5th (the IP)

I've gotten as far as trying to manipulate a do while, for /f token %%a, however, it's where I hit a wall with adding the lines.

Any help would be greatly appreciated and, if in the NYC area, gets a free pizza pie! LOL
